Feign传递header

1. 通过 @RequestHeader(name = "headerName") 来传递

@FeignClient(name ="service-name")publicinterface XXXFeignClient {

    @RequestMapping(value ="/user/getUserTicket", method = RequestMethod.GET)

    String getUserTicket(@RequestParam("id") String id,@RequestHeader(name ="Referer") String referer);}

2. 通过实现 RequestInterceptor 接口

@ConfigurationpublicclassFeignConfigurationimplements RequestInterceptor{ @Overridepublicvoid apply(RequestTemplate requestTemplate) {

        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder

                .getRequestAttributes();

        HttpServletRequest request = attributes.getRequest();

        Enumeration headerNames = request.getHeaderNames();

        if(headerNames !=null) {

            while (headerNames.hasMoreElements()) {

                String name = headerNames.nextElement();

                String values = request.getHeader(name);

                requestTemplate.header(name, values);

            }} }}

然后将自定义的配置类配置到Feign中，就可以实现该Feign中接口Header参数的传递

    @FeignClient(value ="service-name",configuration = FeignConfiguration.class)

    publicinterface XXXFeignClient {

    }
